I’ve been looking around and I’ve come across a lot of great schematics and reference Pictures, but thus far nothing on how to make the trap’s doors open and close. Has anyone tried to do this and if so I’d like to know it’s done.
GhostGuy has a kit coming out this fall with his MightyMicro Controller that will outfit you with all the servos, etc you will need to make your trap open and close, light up, etc.
Cool, hopefully it’ll be in my price range. 
The only person to release an actual motorized trap kit is Hyperdyne and few people have posted sucessful integrations of it into an actual trap. I think I’ve seen a few homebrew setups but for the most part people don’t really do the full “working” trap. Yeah it’s cool and all but really, once it’s finished you play with it a few times, show it off to a few friends and then it just sits on a shelf or on a belt. The time involved in making it work often isn’t worth it. That’s not to discourage you from doing it, working traps are still cool for everyone to see, just realize that there’s a lot of time and not insignificant money needed to pull it off.
